6 - 3n = - 12

what is n?

Answer: n = 6

Step-by-step explanation:

6 - 3n = - 12

Collect like terms

-3n = - 12-6

-3n = - 18

Divide both side by - 3

-3n/-3 = - 18/-3

n = 6

Answer: 6

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

6-3*n - (-12) = 0

Step 1:

Pulling out like terms:

Pull out like factors:

18 - 3n = - 3 • (n - 6)

Equation at the end of step 1:

Step 2:

Equations which are never true:

2.1 Solve : - 3 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2 Solve : n-6 = 0

Add 6 to both sides of the equation:

n = 6

One solution was found:

n = 6
